Mark,
A bit ot.
I have found that these lamps are far more interchangeable with other projectors then most people realize.
Posting lamp specs may help in the sales as well.Lamp: Type: 120W UHE
Life: 2000 hours

A few years ago, I was looking for some cheaper in cost lamps for my Yamaha dlp, no way did i desire to pay the $600 retail.
After some long searches and cross references, I found many other NON clone projectors using the same lamp module.
I found that many PLUS projectors amongst others used identical replacement 120W P-VIP lamps. The only differences were the OEM part numbers on the label.
I went from $600 retail down to under $275.

I even found a step up model with a slight increase of output.
This was a 150W P-VIP and the power supply draw was the same, heat output is no problem, again identical module, no need to even pull the lamp from its housing.

I encourage those looking at purchasing lamps to do a bit of legwork.
You maybe surprised that deals such as Mark’s lamp here can save you some real green
